I'm having some issues out of the center diff lock on my cruiser. It's a 97' w/ 160k miles. I have a CDL switch and the 7 pin mod. This issue is that the center diff locks up just fine when the truck is cool but as soon as I've driven it a while it won't lock at all. It doesn't seem to have anything to do with the outside temp just the temp of the drivetrain.
So, If I jump in the truck after its sat a while and try to lock the diff, it will lock up every time without issue but if I drive it 30 minutes to the trail and try to lock it...no dice. There have been times where I thought it might be locking but the dash light didn't come on so swapped the position sensor with no change. Since the center wont lock (or if it is locked, it's not telling the computer) the axles won't lock. It's really making me crazy...anybody have any ideas? I'm tired of wheeling Subaru style.
